Application filed May 18, 1903. Serial No. 15?,875.

TooZZ whom it may concern:

Be it known that I. CHARLES H. SHEPARD, citizen of the United States.and resident of the borough of Brooklyn. city of New York, in the countyof Kings and State of Xew York. have invented certain new and usefulImprovements in 'lype-Friting Machines, of which the following is aspecification.

My invention relates to typewriting machines and more partitailarly tothe type actions thereof. and the object of said invention is to providea simple and efficient type action wherein the full force or pressure ofthe finger on the key will not be positively applied to the type' inmaking an impression.

To the aboie and other ends which will hereinafter appear. my inventionconsists of the features of construction, arrangements of parts andcombinations of devices to be hereinafter described and particularlypointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicatecorresponding parts in the various views, Figure l is a fragmentarysectional elevation of a suiticient number of parts of a typewritingmachine to illustrate my invention. Fig. 2 a

detail plan view of one of the type bars and hangers, the type bar beingshown in a printinglposition. Fig. 3 is a fragmentary detail sectionalview showing the outer or free end of the type bar. the view being on anerr larged scale. Fig. 4: is a plan view of the same. Fig. 5 is afragmentary detail plan view on "an enlarged scale of a modified.

form of construction. Fig. 6 is a vertical sectional view of the sametaken on the line of Fig. 5. view on an. enlarged scale of the spindleor abutmentshown in Figs. 5 and 6. Fig. 8 is a fragmentary detail sideelevation partly in section of a modified form of type bar embodying myinvention. F ig. 9 is a plan View of the same.

Key levers 1 of any suitable construction are provided with finger keys2, and suitable connecting links 3 are pivoted at 4 to straps 5, each ofwhich surrounds itsassociated key lever. Each of the links 3 in thepresent instance is shown as a two-part link. such as those ordinarilyemployed in the No. 6 Remington machine and the upper end of each linkis connected at 3 to a crank arm 6 Fig. 7 is a detail perspective.

' of a type bar or printing instrnmentality 'that comprises twomemberszone, body portion 7 that is pivoted by its trunnions 8 to ahanger 9, and the other a type carrying member 10. In the constructionshown in Figs. 1. 3 and 4, the body portion of the type bar is providedat its free with a bearing portion or socket 11 that extends atsubstantially right angles to the lengths of the body portion of the barand receives the loosely disposed type carrying member or block 10therein. The type carrying member is recessed at 12. and a pin 13extends through the bearing portion of the bar and into the recess so asto limit the movement of the type carrying member relatively to the bodyportion of the bar. and prevent it from turning in its bearing.

Each yoke-like type bar hanger 9 has the side arms thereof extendedtoward the print-- ing point so as to form supporting arms 9 nature of aspindle that extends between the supporti: g portions or arms 9* of eachhanger and constitutes a connection between them and which projects intothe path of the body portion 7 of the associated type bar, in the.movement of a bar to the printing position, as clearly represented inFig. 1. Each spindle 1% is preferably sheathed as indicated at 15 with apadof comparatively soft substancesuch as leather, felt or the like. toreceive the impact of the body portion of the bar in its movement to theprinting position and thus avoid the objectionable nolse which wouldoccur by an impact of the bar directly against the metallic spindles 14in the movementsof the bars to the printing position. From-anexamination of Figs. 1 and 3 it will be understood that the dispositionof eachabutment 14: is such that; the body portion 7 of the associatedtype bar reaches contact therewith, or with the sheath on said abutment,before the type arrives at the printing position or contacts with aplaten 16, or the paper thereon. The momentum of the type bar in movingto the in-its bearing. thus bringing the face of the type to theprinting ortion 7 of the bar as been arrested by for a stop or abutment1 L which is in the its abutment 14. It will therefore be seen printingposition is, however, suflicient to enable the type carrying member toslide point after the body' be positively applied to the type. I I Whilethe various type bars throughout the systenrmay be constructed inaccordance with my invention, it should be understood that the invention'is particularly valu-' able for those type bars which carrythe types ofthe punctuation marks such as the period and comma inasmuch as the typesfor these marks or characters are liable to puncture the paper in theordinary operation of the machine, and by my invention the liability ofthe sheet being punctured, is overcome. The invention, however, is alsoof value when applied to all of the type bars of the system inasmuch asit enables the type carrying member of each bar to recede rapidly'fromthe printing oint independently of the body portion'o the bar after theimpression is made, and positively prevents the operator from holdingthe type at the printing point by a long,--following and lingerin strokeupon the key, thereby avoiding a burring of the imprint and providing aclearer and better character of work. I

In the construction represented in Figs. 5 and 6 the spindle or abutment14: is providedwith a head 17 and a screw-threaded end 18. This spindleis loosely seated in bearings in the arms or supports 9 of itsv hanger;with the head 17 on the outer side of one arm'9 and a screw-threaded endprojecting beyond the other support 9" where it cooperates with a nut 19which, when Screwed tight, exerts a pressure to maintain the spindle inthe position to Which it is turned. An eccentric 20 is formed on each spndle intermediate of the ends thereof andthis eccentric is sheathed --sindicated at 21 with a pad of comparatively soft material such as feltor leather, against which the body portion 7 of the associated type baris adapted to strike. It will be understood that by turning the spindle,different portions of the eccentric 20, which constitutes the abutment,will be interposed in the path of the bodyportion of the type bar in itsprinting movement; that the point of arrest of the body portion. varied,and the force of impactof the type carrying member may in a degree bercgulatcd. The adjustment of the eccentric 2O likewise compensates forwear between the' abutment and the body portion of the type bar at thepoint of impact between the two.

In the construction illustrated in F 8 and 9, a modified form of typebar is shown wherein the body portion 7 isbifurcated at its free end,asindicated at 21, and receives of the bar may thus be within thebifurcation a portion of the type carrying member. A pivot extendsthrough the two members to pivot ally unitc them and to form a knucklejoint that enables the type carryingmember 10 to swing to the-printingposition after the body portion 7 of the bar has been arrested by itscooperating abutment. 22 of the type carrying member is adapted tocontact with the end wall of the bifurcated portion 21 of the bar, asindicated at 24:, so as to limit the movement of the type carryingmember in one direction with relation to the body portion of the bar. Itwill be observed thatv in Figs. 1, 2, 3 and at a sin-.

maintain the hangers in their adjusted posi; tlons. In bothconstructions shown, it Will I .be seen that the ty 1e block or typecarrying member has a limited movement relatively to the body portion ofthe bar in the general direction of movement of the bar" and atsubstantially right angles to the length thereof, to complete theprinting stroke solely by momentum after the body of the bar has beenarrested. I

From the broad aspect of my invention it is immaterial by what portionof the machine the. abutment which cooperates with each type bar iscarried, and it is immaterial what the construction of this abutment is,so long as it arrests the body portion of the type bar before the typecarrying member thereof reaches the printing point.

It should be understood changes may be made without departing from thespirit of my invention.
